ISPconfig IMAP slower than naked install

some time ago , I did a test install of ispconfig (around december) on Etch running as a VM on ESX. Right now I don't seem to find the version number of ispconfig in the control panel though.

A direct comparison of the IMAP speeds shows an extremely slow IMAP of the ispconfig machine. (getting 1200 SPAM-Mails takes about 5 minutes - Ethernet connected). A physical Debian machine does this in seconds.

I took a look at the imap config: MAXDAEMONS = 40 , and MAXPERIP = 20 , so that seems OK. CPU load is under 1% for IMAP.

ISPConfig writes just config files, not more and not less, so the speed of deamons has nothing to do with ISPConfig. For example, ISPConfig is no IMAP server and does not provide IMAP services at all. Your IMAP server is e.g. courier or dovecot or cyrus or any other imap daemon.

Tools > Software version. But as stated above, this has nothing to do with your problem.

Are you sure that the problem is related to IMAP at all? Maybe you enabled spam and antivirus scanning?
